Abstract
A projectile launcher includes a housing including a launching section. The launching section includes a first spring and a second spring, a piston coupled with the first and second springs, and a charger that compresses each of the first and second springs against the piston within the launching section. The projectile launcher further includes hollow barrel that extends to a front end of the projectile launcher, a projectile loading area configured to receive and load a projectile in position with a firing end of the piston and the barrel, and a trigger. Compression of the first and second springs by the charger is released in response to actuation of the trigger, where release of the compression of the first and second springs forces movement of the piston toward the projectile loading area so as to launch a projectile loaded within the projectile loading area through the barrel and from the projectile launcher.
